Abstract

LA REGENERACION DE UN ELEMENTO GRANULAR SE LLEVA A CABO MEDIANTE LA FORMACION MECANICA DE UNA PASTA DEL ELEMENTO EN UN LIQUIDO Y LA SEPARACION DEL LIQUIDO DEL ELEMENTO GRANULAR A BASE DE HACER ROTAR RAPIDAMENTE A UN ELEMENTO SEPARADOR QUE TENGA PEQUEÑAS ABERTURAS, A TRAVES DE LA PASTA, A MEDIDA QUE EL FLUJO DE UNA PASTA DE GRANULOS LIQUIDA ES RETENIDA A TRAVES DE LAS ABERTURAS, CON LO QUE EL MOVIMIENTO PRODUCE UNA ACCION DE LAVADO QUE MANTIENE LAS ABERTURAS LIMPIAS DE GRANULOS.
